PRESSING ELEMENT FOR LAUNDRY AND GARMENT PRESSING MACHINES Original Filed Feb. 15, 1929 Patented May 19, 1931 UNITED STATES PATENT, OFFICE I ERNEST DAVIS, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY INC., 01? SYRACUSE, NEW YORK, A CORPORATION OF'NEW YORK PRESSING ELEMENT FOR LAUNDRY AND GARMENT PRESSING MACHINES Application filed February 15, 1929, Serial No. 340,139. Renewed October 8, 1230.

This invention relates to platen pressing elements as heads or bucks of garment and laundrypressing machines, particularly heads or bucks of light weight construction consisting of a light main plate and light sheet metal plates which form the heating chamber of the element, and has for its object a particularly simple, eflicient and economical construction by which the conduit, from which a fluid, as steam or air, or both, is projected through the pressing face, is secured to the main plate of the head or buck, or assembled in the head or buck construction.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate correspondin parts in all the views.

igure 1 is a plan view of a press head embodying this invention.

Figures 2 and 3 are respectively a central longitudinal and transverse sectional views taken of Figure 1, the latter being on an enlarged scale.

Figure 4- is a perspective view, partly broken away.

Figure 5 is an enlarged fragmentary cross sectional view through the steam conduit and contiguous parts.

Figure 6 is a fragmentary side elevation of a pressing machine embodying this pressing elementa This pressing element comprises a rigid main plate having a lengthwise slot, a conduit for a fluid, as steam or air, having. a lengthwise rib fitting the slot and formed with jet openings through which a fluid as steam or air may be projected from the conduit to the pressing face, a sheet metal plate- 2 designates the lengthwise slot formed therein and opening through its upper an lower faces.

3 is the conduit for a fluid, usually steam,

for steaming the garment, although air may .margin of the plate 1 along the slot 2 (Figure 2). It also has additional shoulders 6 under which extend the margins of a slot formed in the sheet metal plate tobe presently described.

The rib portion 4 is formed with perforations or jet openings 7 therethrough leading from the interior of the conduit to the pressing face of the plate 1. r

8 is a crowned sheet metal plate overlying the plate 1 and secured atits margin's 9 thereto as by welding, the plate 8 confining a cha mber for a heating medium as steam. The plate is formed with an inlet 10 and an outlet 11 for the steam.

The plate 8 is formed with a number of internal corrugations 12, the crowns 13 of which are secured as by welding to the plate 1. The corrugations terminate short of the ends of the crowned portion, Figure 1,

so that the steam can be distributed through by'a cover plate 15 secured at its margins 16 as by welding, The corrugation beneath the cover plate is preferably packed with a heat distributing material as copper wool.

- 17 is a conduit communicating with the steam chamber formed by the plate 8 and with the conduit 3, the conduit 17 being connected to a valve casing 18 mounted on a portion 19 of the conduit 3, which portion extends through the cover plate 15. The portion 19 is formed with an inlet passage 20.

The movable valve member in the casing 18 is operated by a hand lever 21.

22 is a carrler plate to which the yoke lever 23, Figure 6, of the pressing machine is secured, the carrier plate being slidably mounted on studs 24 projecting from blocks 25 secured, as by welding in depressions or corrugations in the plate 8. Compression springs 26 are interposed between the carrier plate 22 and the blocks 25 to yield when the head oes under heavy pressure on the buck 27 0% the pressing machine.

The head or the yoke lever is actuated by an% suitable mechanism.

he pressing element is light, strong, and economical in construction, and the steam conduit 3 is applied thereto in a particularly simple and economical manner.

What I- claim is:

1. A pressing element for pressing machines comprising a plate having a pressing face and a lengthwise slot opening through its 0 posite faces, a conduit mounted on the plate and having a'lengthwise rib portion fitting the slot and formed with jet openings through which a fluid may be discharged from the conduit to the pressing face.

2. Apressingelement forpressingmachines comprising a plate having a pressing face and a len hwise slot opening through its opposite aces, a conduit mounted on the plate and havin a lengthwise rib portion fitting the slot an formed with jet openings through which a fluid may be,discharged from the conduit to the pressing face, a sheet metal crowned plate secured at its margins to the first plate and formed with internal corrugations, the crowns of which are secured to the first plate, the corrugations terminating short of the ends of the crowned plate, one of said corrugations having a slot alined with the slot in the first plate and the rib portion of the conduit extending through said slot.

3. A pressing element for pressing machines comprising a plate having a pressing face and a lengthwise slot opening through its opposite faces, a conduit mounted on the late and having a lengthwise rib portion fitting the slot and formed with jet openings through which a fluid may be discharged from the conduit to the pressing face, a sheet metal crowned plate secured at its margins to the first plate and formed with internal corrugations, the crowns of which are secured to the first plate, the corrugations terminating short of the ends of the crowned plate, one of said corrugations having a slot alined with the slot in the first plate and the rib portion of the conduit extending through said slot, and acover plate for the open side of the corrugation in which said conduit is located.

4. A pressing element for pressing machines comprising a plate having a pressing faceand a lengthwise slot opening through its opposite faces, a conduit mounted on the plate and having a lengthwise rib portion fitting the slot and formed with jet openings through which a fluid may be discharged from the conduit to the pressing face, a sheet metal crowned plate secured at its margins to the first plate and formed with internal corrugations, the crowns of which are secured to the first plate, the corrugations terminating short of the ends of the crowned plate, one of said corrugations having a slot alined with the slot in the first plate and the rib portion of the conduit extending through said slot, a cover plate for the open side of the corrugation in which said conduit is located, and a packing material in said corrugation around the conduit.

5. A pressing element for pressing machines comprising a plate having a pressing face and a lengthwise slot opening through its opposite faces, a conduit mounted on the plate and having a lengthwise rib portion fitting the slot and formed with jet openings through which a fluid may be discharged from the conduit to the pressing face, a sheet metal crowned plate secured at its margins to the first plate and formed with internal corrugations, thecrowns of which are secured to the first late, the corrugations terminating short of the ends of the crowned plate, one of said corrugations having a slot alined with the slot in the first plate and the rib portion of the conduit extending through said slot, a cover plate for the open side of the corrugation in which said conduit is located, the conduit having a portion extending through the cover and formed with an inlet for a fluid and a control valve mounted on said portion of the conduit.

In testimony whereof, I have hereunto signed m name, at Syracuse, in the county of Onon aga and State of New York, this 13th day of Feb., 1929.
